SPRINGFIELD, Mass. (AP) – A key witness at the murder trial of a Hells Angels motorcycle club member charged with killing three men testified Wednesday that he helped dispose of the victims’ dismembered bodies.

David Casey, 65, of Canaan, N.Y., testified in Hampden Superior Court in Springfield that he helped Adam Lee Hall bury the remains in a 4-foot-deep trench on private property in Becket in Berkshire County.

Hall, 36, of Peru, Mass., and two other men are charged with fatally shooting David Glasser, Edward Frampton and Robert Chadwell in Pittsfield in August 2011. Prosecutors say Hall wanted Glasser dead so he couldn’t testify against him in an unrelated assault case, and the others were killed to eliminate witnesses. Casey is charged as an accessory.

Hall’s attorney Alan Black has said there’s no physical evidence linking Hall to the killings.

Casey said he knew Hall because he’d done excavation work for him. He said Hall came to his home and told him about the killings. He said he helped Hall because he feared him.

Casey said Hall told him his gun jammed the first time he tried to shoot Glasser and Glasser ran into the woods. Hall said one of his companions brought Glasser back, Casey said. He said Hall told him Glasser begged for his life, but Hall told him he had warned him what would happen if he testified against him, then shot him.

Casey said he used his excavation equipment to dig the hole in which they buried plastic garbage bags containing the bodies.

Black asked Casey about differing statements he has made to police and whether he cooperated with authorities to save himself from more serious charges.
